First jack the front end and remove the wheels. second there are 2 bolts that hold the calipers in these are on the inside of the caliper, one at the top and one at the bottom, they could be hex head or torx head bolts. remove these and tap the caliper loose and it will slide away from the rotor. remove old pads then you need a c clamp and you have to compress the caliper pistons back in to make room for the new ones. once this is done and the pads are in the calipers, slide the caliper back over the rotor and tap lightly into place. then replace bolts and you are all set. compressing the pistons will save you opening the lines to bleed the brakes.
